#DAC of CO2 from the atm. is being explored as a tech. that can contribute to the goal of reaching #NetZero CO2 emissions.
A new study led by @DonglongFu1 showed that the use of zeolitic materials are feasible for DAC when it is integrated with H2O harvesting.
🧵 1/7
"A combination of a commercially available desiccant, AQSOA-Z02A, and a mordenite-type zeolite (MOR) enables
continuous operation of a designed #DAC system comprised of two
parallel units with a regeneration temperature of 100°C," research finds. 2/7
Furthermore, "the system
using pure #zeolite alone requires regeneration at temperatures between 200°C and 300°C." 3/7
"Techno-economic analyses of 12 process
scenarios reveal that the energy requirement of the best scenario
investigated is 71 GJ/tCO2, while the conventional pure zeolitebased system requires 200 GJ/tCO2." #DAC 4/7
Research declared that, "the optimized system gives a
cost between $246 and $568 per ton CO2 #captured, depending on
the energy costs, while system operates at sub-0°C temperatures or with
integration of water harvesting, respectively." #DAC 5/7

🚨Scientists Make Strides in Resurrecting Woolly Mammoths to Combat Climate Change🚨
A pioneering biotech firm has successfully genetically modified mice, marking a key step toward developing mammoth-like elephants to restore Arctic ecosystems & slow permafrost thaw.🧵1/10
2/ Colossal Biosciences (@colossal), a Texas-based biotech firm, has engineered mice with mammoth-like traits. Their ultimate goal? Create herds of cold-adapted elephants that could help protect permafrost and reduce carbon emissions.
3/Why does this matter for climate change?
Permafrost holds huge amounts of C. When it melts it emits CO2 & CH4—increasing global warming. Mammoths once maintained Arctic grasslands, which helped insulate the permafrost. Colossal wants to bring this process back via neo-mammoths

The Frontier Buyers has teamed up with carbon removal developer Phlair, committing to invest $30.6 million in electrochemical direct air capture to remove 47,000 tons of CO2 from 2027 to 2030.
B.C. Centre for Innovation and Clean Energy launched Canada’s first CDR fund, offering $3M to support early-stage, hard-tech carbon removal solutions for decarbonizing B.C. and Canada.
"Geoengineering isn't just a climate issue—it's a geopolitical chess game. Only US & China have power to unilaterally deploy #SAI at scale."
Will they race to control skies or seek climate diplomacy? New study explores 4 futures🧵1/9
2/ SAI could cool the planet—but who controls it controls global climate security.
Key risks of unilateral deployment:
🔴 Termination shock
🔴 Environmental disruptions
🔴 SAI as a potential weapon
🔴 Geopolitical leverage—both a threat & opportunity
3/ This creates a security gap:
The US & China are locked in great power competition, yet neither has a clear strategy on SAI.
Who moves first? Who controls the stratosphere? The dilemma: Deploy & gain influence—or deter & risk falling behind?
